One of the main genetic abnormalities associated with breast carcinogenesis is the loss of genetic material from chromosome arm 16q. Different groups have identified two regions (16q22.1 and 16q24-ter) that are frequently deleted in primary tumors, suggesting the presence of tumor suppressor genes i

β¦ Synopsis
Loss of heterozygosity (LOH) on chromosomes 3p and 9p has
been documented in a variety of malignancies, which suggests the presence of tumor suppressor gene loci on these chromosomes. We have studied 77 oral carcinomas for LOH using 16 microsatellite markers distributed over 5 human chromosomes.

We conducted linkage analysis of 64 multiple-case families with early-onset bilateral breast cancer using DNA markers on chromosome band 1p36. Evidence against tight linkage was obtained using a dominant model for transmission (summary LOD scores at recombination fraction Ο 0.000001 were -4.71 for D
The most frequent genetic aberration found in transitional cell carcinoma (TCC) of the bladder involves chromosome 9. Loss of heterozygosity (LOH) analyses show deletions of both chromosome 9p and 9q, while in situ hybridization studies suggest a significant percentage of tumours with monosomy 9. To
Deletions in the short arm of chromosome 3 have long been known to be common in many tumor types, including carcinomas of the lung and kidney. Small interstitial deletions of the proximal-central region of 3p, with band 3p14 as a minimal common deleted segment, have recently been shown to occur in a
Loss of heterozygosity on chromosome 9 has been reported in a variety of human cancers. The cyclin-dependent kinase inhibitor p16 gene, mapped on chromosome 9p21, is presumed to be the tumor-suppressor gene localized in this chromosome. The aim of our study was to determine, in 26 Barrett's adenocar
